Displaying multiple information on map

Hi guys I'm really new to the arcGIS and spatial analysis and encountering the following porblem:

I have a map base and a dataset to define the boundries of districts in my city. I have quite a lot of statistics (e.g. population, median income) for each of the districts. Previously i used the "polygon to raster" function to display a single statistic on the map. HoweverI don't know which function could help me visualise two (or more) statistics at the same time on map.

I have seen some graphs to represent two statistiscs in this way: on the map, the first statistic is used to colour the districts, while the other statistic is used to colour circles hovering above the districts. Could anyone tell me how to do this (or other ways to display multiple stats) please?

You dont need to convert vector data to raster to show vector attributes.The best way to show attributes in different way is to use Symbology tab in layer Properties where you can choose among specific way of symbolizing.You can read more about symbolizing in About symbolizing layers to represent quantity online help topic and consecutive topics.

To show graduated colors on the botton and pie charts above, the simplest way is to copy and paste the same vector layer in one data frame in Table of Contents. So you have to layers in ToC - one can be symbolized using Graduated colors and second using Pie Charts. Here's an example:[ATTACH=CONFIG]18476[/ATTACH]
